@Super_pickle hmm according to that image you are seeing up to 5 frames before your current position (frame 19th) If you want to see the drawings instead, press the “onion skin” diamond button on the timeline next to the playback controls. That button enables the onion skin “match-frames to drawing” which changes from an absolute frame count to a relative drawing count.

You can also increase the amount of onion skins you see before or after your current frame on the preferences
